3 Claims.

This invention relates to electric dry shavers and more particularly itrelates to an electric dry shaver which is shaped like the ordinarysafety razor and which can be operated in the same manner as theordinary safety razor but without the use of soap or the like.

-Like a number of electric shavers now on the market, the shaveraccording to the present invention works on the clipper principle havingas it does a stationary clipper plate provided with teeth and a movableclipper plate also having teeth and adapted to reciprocate with respectto stationary plate. `When the plates which are disposed like the bladeof a safety razor are drawn across the face whiskers will be directedbetween the teeth and will be sheared oi.

Practically all of the manufacturers of electric dry shavers warn theircustomers not to 'be discouraged with the lrst results of use since itfrequently takes several weeks and sometimes months before the newstrokes and manipulations necessary can be mastered. With the presentinvention no practice is necessary since the device is operated with thesame strokes and manipulations as are used with the ordinary safetyrazor.

The present invention is further unlike the electric Shavers now on themarket in that the stationary and movable clipper plates are disposed soas to be in full view at all times so that the operator can see at alltimes how the razor shaves with each stroke. l

It should already be manifest that one object of the present inventionis the provision o-f an electric dry shaver which can be operated in thesame manner as the usual safety razor but without the need for soap orthe like'. Another object which is apparent is the provision of anelectric dry shaver yso designed that the operator can see how the razorshaves' with each stroke.

Another'object of the invention is to provide an electric dry shaver inwhich the moving clipper plate is not covered and is so arranged as tobe easily replaced.

Still a further object is to provide a shaver in which the moving plateis narrower than the stationary plate and is disposed above thestationary plate. s

Other objects will be apparentfrom the following description'andaccompanying drawings.

In the drawings:

Fig. l is an enlarged perspective view of one embodiment of theinvention showing only the upper portion of the shaver to which theinvention relates.

Fig. 2 is a similar view with the movable clipper plate elevated to showthe manner in which the stationary plate is secured.

(Cl. lib- 43) Fig. 3 is an enlarged perspective view'of the sameembodiment with both the stationary and movable plates removed andshowing one of the spring guides.

Fig. 4 is an enlarged front elevation of the shaver shown in Figs. l to3.

Fig. 5 is an enlarged side elevation.

Fig. 6 is a toplplanview also enlarged.

Fig. '7 is an enlarged detail view of one manner of connecting theactuator to the moving plate, and

Fig. 8 is an enlarged side elevation of another embodiment utilizing.movable and stationaryclipper plates which are slightly curved in crosssection. j

'I'he electric dry shaver illustrated inthe drawings has a handle 2which may be of hard rubber, bakelite or any suitable insulationmaterial. The handle preferably should becomparatively small and narrowso as to 4simulate as closely .as possible the size and shape of thehandle of the ordinary safety razor. The handle houses a small electricmotor (not shown) which may be of the type used in dry Shavers and whichis connected by suitable -mechanism tc impart a limited reciprocatorymovement to an actuator d which extends upwardly from' a rectangularwell in the upper end of the handle 2.

Formed as to t in the well is a supporting member 6 of metal or thelike. The member '6' may be die-cast or even stamped and, as shown, haschannelled end portions 8 (see Figs. 1 and 5 for example), and topvflange portions I which extend over the -top `surfaces of the handle 2on each side of the rectangular well.

The supporting member has a central opening for the actuator 4.

The reference numerals I2, I 2 indicate' supporting posts of metal orother suitable material.

The bases of these supporting posts l2, I2' are preferably square incross section and they are snugly disposed in the channelled endportions 8 of the supporting member 6 to which they `are secured bysuitable means such as by the screws y.

I4 and I6.

The outer sides of the supporting posts I2,. I2' are beveled inwardlytowards their upper ends to permit an inward swinging motion of springmembers generally indicated by the reference numeral I8. These may besecured nearer thebase of the supporting posts I2, I2 by the- The springmembers I8 may be of the latter being slightly narrower in width. Eachof the plates is provided along its longitudinal edges with teeth 28, 28so that when the movable plate blade is reciprocated longitudinally aclipping or shearing action between the teeth of the plates iseiiected.

The stationary plate 24 is mounted on the supporting posts l2, 2f bymeans oi' screws 30 as shown in Figs. 2 and 4 most clearly. The

`screws are also used to hold the spring guides 32 in place, the innerends of the latter being disposed between the stationary plate and thesupporting posts when the device is assembled. One of these springguides 32 is shown in perspective in Fig. 3. They have arectangularopening through which the spring members I8 pass andtheir'purpose is to limit the outward motion of the spring members. Asshown in Fig. 2, for example, the ends of the stationary plate 24 haverectangular recesses 34 to permit greater movement of the spring member.The stationary plate 24 also has a central opening 36 through which theactuator 4 extends.) The opening 36 is large enough to permit fullreciprocatory movement of the actuator Il.

The movable plate 2B is disposed above the stationary plate 24. It isreciprocated longitudinally by the actuator 4 which may engage a recessformed in the underside of the movable.

plate. As shown in Fig. 'Z the under side of the movable plate may beprovided with a rectangular ridge 3&3, the actuator Il engaging in thewell bounded thereby;

' The movable plate 2@ is held against the stationary plate `by theif-shaped upper ends of the spring members'iti, the under edges oi thecross portions oi which engage the upper surfaces of the movable plateadiacent small rectangular cut-outs d@ in the ends of the plate (Fig.2). The

` vertical or upright portion of the T-shaped spring members iti engagein these cut-outs. Small up-turned portions l2 adjacent the cutv outs d@(also see Fig. 2) aid in `ireeping the movable plate in place on thestationary plate.

From the above description it is probably now apparent that the deviceoperates in the following manner. The actuator l driven by the motor inthe handle reciprocates the movable plate 2@ along its longitudinalaxis. As the movable plate moves rst in one direction and then in theother, it presses the spring members lil outwardly. The spring membersare tensioned so that they will aid in returning the plate to neutralposition. The inward and outward movement oi the spring 'members islimited by the spring guides 32.

greater cross sectional curvature as this aids in keeping the teeth ofthe plates in contacting position when the movable plate is held down bythe T-shaped spring members.

Naturally a reciprocatory movement of the movable plate may be/eected bymeans other n ari-1,219 v plate 24 and a movable metal clipper plate 26,

than the actuator 4. For example, the reciprocatory movement may beeffected by having a rotatable shaft on the end of which a pin iseccentrically disposed. This pin enga-ges a slot or recess in themovable plate.

The device illustrated and described is of simple construction. Sincethe movable plate is disposed above the stationary plate and is notcovered by a protecting member, it may be easily replaced. At the sametime it is possible for the operator to usethe device by employing thesame strokes as are customary with an ordinary safety razor. Theoperator can see at all times how the shaving is progressing and obtainan excellent shave without previous practice.

It is obvious that modicatlons of the invention disclosed can be madewithout departing from the inventive concept, and I do not intend to belimited except asindicated in the following claims.
